54                    PAPILLARY CARCINOMA OF RENAL PELVIS

No clinical information is available.

The specimen is of a kidney measuring 9 cms in length and has been partially opened to disclose a large papillary carcinoma of the renal pelvis growing as a pale friable mass into the pelvis. There is a good deal of intrarenal hydronephrosis from obstruction to the ureteric origin and there are some petechial haemorrhages beneath the mucosa in a few places.
